SPECIFICATION forming part of Letters Patent No. 530,078, dated December 4, 1 894.

Application filed December 29, 1 893 Serial No. 495,116- (No model.)

To 00% whom it may concern.-

Be it known that I, CHARLES W. AMMER- MAN, a citizen of the United States, residing at Greenwood, in-the county of Sussex and State of Delaware, have invented a new and useful Combined Sash Lock and Holder, of

to lock or hold the sash' at any desired point,

of elevation or adjustment.

With the foregoing general objects in view, the invention consists in certain features of 7 construction hereinafter specified and parperspective of the operatingshaft.

ticularly pointed out in the claim.

Referring to the drawings-Figure 1 is a vertical longitudinal sectional View of a portion of a sash-rail and window-frame, the for- .mer being provided with a combined holder and lock constructed in accordance with my invention. Fig. 2 is a vertical transverse sectional view of the sash-rail. Fig. 3 is an edge-view of the sash. Fig. 4: .is a detail in Fig. 5 is a similar view, of the spring-latch.

Like numerals of reference indicate like parts in all the figures of the drawings.

In the practice of my invention, I either provide the inner surface of the side rail 1 of the window-frame with a series of transverse notches or teeth 2, whose outer edges are inclined upwardly, as shown, or, if preferred, I may form a metal strip constructed as stated, and attach the same to the inner surface of the side-rail of the window-frame. In either instance however, I provide at the lower end of the series of teeth, a transverse plain kerf or recess 3, whose object will hereinafter appear.

The outer edge of the vertical rail of the sash-frame I provide with a shallow elongated recess 4, which at its lower end merges into a deeper recess, cavity or pocket, 5, the front and rear walls of which are provided with bearing openings, the rear or enter one of which does not extend entirely through, so that it cannot be perceived from the outside. The rear bearing-opening is occupied by a bearing-sleeve, 6, and the front opening is surrounded at its exterior by a perforated washer or Wear-plate 7, the same being suitably secured to the face of the sash-rail by screws or other ordinary means.

Jou rnaled loosely in the two bearings of the cavity is a cylindrical transversely disposed shaft 8, whose front end extends in front of .the sash and is either shaped to form or has arranged thereon, a handle 9, by which said shaft may be operated. Between its ends the shaft is provided with a perforation, and receives the bored hub, 9, of a rectangular bridle or frame 10, said hub being perforated to agree with the shaft and being rigidly con nected therewith by means of a transverse pin or screw 11.

Seated in the recess 4 and extending across the opening in the cavity 5 therebelow, is a flat straight spring 12, which opposite said cavity has its lower, end outwardly or laterally bent to form a locking-end or catch 13, that normally projects beyond the face of the side-rail of the sash in which it is located. The upper end of the spring is perforated, and through the perforations, screws l-f are passed into the face of the rail or rather into the bottom of the recess l. This manner of fastening, leaves the lower end of the spring free, so that when not otherwise influenced, the catch at said end, will engage with one of the inclined notches formed in the side rail of the window-frame,or, if the-sash be wholly lowered, said catch will engage with the lower transverse kerf therein. The lower end of the spring passes. through the rectangular bridle or frame 10, so that by partially roit will be obvious, that, as before stated, the

kerf will be engaged by the spring-catch, so that the said sash is efficiently and securely locked against raising. It will also be obvious that no person from the outside can from an inspection of the exterior of the sash gain any knowledge as to the location of the lock or the manner of its operation, so that unauthorized persons seeking an entrance will not meet with the success they do when the lock is located upon the meeting-rails of the sash and a small piece of glass need only be cut out in order to operate the same.

When the sash is completely closed, in order to raise the same, it is simply necessary to partially rock the shaft through the medium of its handle, when the catch will be withdrawn and the desired object accomplished. Immediately upon a release of the window the catch will engage with one of the inclined teeth or notches of the window-frame, and thus be held against further lowering until the catch is again withdrawn. On the other hand, however, the sash may be readily further elevated or raised by the operator without touching the catch, the inclination of the notches or teeth permitting such an operation.

The object in arranging the look upon the sash, to be carried thereby, is that the projecting handle-portion 9 may serve as a means of raising the sash, whereby the operator may use both hands in accomplishing this object. It is obvious that upward pressure may be applied to the sash by the hand which grasps this handle without interfering with the proper manipulation of the lock. Furthermore, inasmuch as the spring latch is disengaged from the notched plate by turning the lower end of the pendent handle 9 inwardly, the operation of disengaging the lock does not require an exertion independent of that which is necessary raise the sash. Furthermore, the spindle 8 with its attached handle is secured rotatably in the sash by means of the bridle which is fastened to the spindle by means of a pin 11, and therefore the placement of this pin adjusts the bridle to the spindle and secures the spindle in its bearings in the sash, and the above arrangement of parts may be accomplished before the sash is placed in the frame. Furthermore, when the sash is being arranged in the frame, the

hand which is employed to hold the locking device in its retracted position maybe employed also to assist in supporting and guiding the sash. Furthermore, by arranging the spindle of the lock perpendicular to the plane of the sash and mounting it in bearings in one of the side bars of the sash, the exterior handle 9 is concealed by the side bar from the outside of the window.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a very simple combined lock and holderfor sashes; that the same may be cheaply constructed and. sold, and is readily applied to any of the sashes ordinarily used.

Having described my invention, what I claim is- The combination with a vertical notched plate permanently secured to a window frame, of a spring latch secured at its upper end to the outer edge of the side bar of a sash and provided at its lower end with a perpendicularly disposed outwardly bent locking end or catch to engage one of the notches in said plate, a spindle arranged perpendicular to the plane of the sash, and mounted in bearings therein, said spindle terminating beyond the inner surface of the sash in a depending handle, a bridle having a sleeve to receive said spindle within a cavity in the side bar of the sash and having a cross-bar to bear againstthe outer surface of the spring latch, and a pin engaging registering perforations in said sleeve and spindle, whereby when the lower end of the handle carried by the spindle is swung inwardly, the cross-bar at the outer end of the bridle is swung downwardly and disengages the locking end or catch of the spring latch from the notched plate, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

CHARLES W. AMMERMAN.
